Designing a Content Cluster

Arrayed concave dishes with unique curvature each capture distinct beams; no overlapping focus, symbolizing content clusters covering non-overlapping sub-queries
The core of content clusters is covering non-overlapping sub-queries, ensuring each hits a dedicated page

IN ONE SENTENCE

A content cluster exists so that every sub-query produced by query fan-out lands on a page written to answer it.

A content cluster is a hub page plus interlinked detail pages. It suits passage retrieval: the hub carries concepts and relationships while each detail page answers one sub-question fully, so sub-queries from query fan-out are more likely to hit one of them.

OUR POSITION

A cluster's value is coverage without overlap, not page count. Two pages on one intent compete, and an uncovered sub-question is simply forfeited — so designing a cluster starts with listing sub-questions, not deciding a page count.

01

Which page types belong in a cluster

The hub: what sub-questions this subject contains, how they relate, and links to each detail page.

Concept detail pages: one concept each, covering definition and position.

Operational detail pages: how to do one specific thing and how to judge it.

Measurement detail pages: how it is measured and where it is misread. The three types map to questions at different stages.

02

Two common design errors

Overlapping detail pages: two pages on one intent, competing. The test is writing out each page's target question — if one sentence covers both, merge them.

A hub with no detail pages: it mentions everything and resolves nothing, so it is not the best answer to any sub-query.

03

Judging the size

Yield in this category concentrates in the top ten — around 13 monthly clicks per keyword at positions 1–3 and near zero beyond 11 — so cluster size should follow from how many sub-questions can realistically reach the top ten, not from a target page count.

If the sub-question list yields eight real questions, the cluster is eight pages. Padding it to twenty makes the last twelve rephrasing.
